Hello,
I am planning to display a string of characters using 16x2 LCD module.
Please see the photo below. I put the compiled code (hex file) into Proteus simulation. It does running normal.
But when I put the code inside my PIC18F4550 connected to all 16 pins of the LCD (TGK model bought from Cytron), there was just a block of black display appeared. I have check all the solder points, there are no short circuit between all 16 pins.
Simulation OK, but real hardware NOT OK.
How????
